Bad news:* Changing the external tile-sets breaks any blueprints that use them.* TileD doesn't handle tiles with different sizes very gracefully, so you'll have to decide for yourself what to do about making two-tile doors.

Goodish news: twoelk - your rotated trees idea was important; I made the change, even though it broke a couple of my blueprints. I'd rather not do that again, so I cleaned up everything else I could think of and made minetest_game.tsx set as accurate as I could.

For our purposes this feels like a bit of a design flaw in TileD. Not a deal-breaker for me. This is still much better than graph paper or pushing pixels; but it does mean I'm leaving the exported tileset alone after this week.

You can add any tiles you want directly in your own maps or blueprints (same as I did to put these together). If you want to do that, just click map -> new tileset and follow the instructions.

I've been playing with a voxel image editor, Goxel, as a better way to make blueprints. So far it's been easy to use and a much more direct way to visualize my builds before I put game-resources and time into them.

I've been taking a bit of inspiration from the Tiny House movement. There are numerous images and blueprints for extremely modest homes, many of them well designed for a person who wants to build something both attractive and efficient in a short time-frame.

For a creative challenge, try working with the question: "What can you do in a 10x10x10 (or smaller) block?" (Keeping in mind that at minimum a bed, stove, and room for a chest are mandatory.) That's not a lot to work with, but it's a good fit if you want to keep things creative when you start somewhere new.

Mese maze:It is easy to go from top left to bottom right: Move only east and south, you can use F5.Reaching top left from bottom right is very difficult if you don't have a map of the labyrinth.I can use this as castle entrance: The castle is built on the top left and the labyrinth is hidden so that you can't see it on a map. Leaving the castle then is easy but entering it is not.It's a binary tree maze. http://www.astrolog.org/labyrnth/algrithm.htm
